Covid19 - A message to our business customers

We know that COVID-19 has brought with it some very difficult conditions, especially when it comes to businesses' ability to trade and generate income.


As a company which provides an essential public service, we are acutely aware of the huge importance of maintaining our water and wastewater services during these unprecedented times. To achieve this, we've been running a dedicated Crisis Management Team for several weeks to strategically coordinate all our activity and ensure continuity of service.
